For 12x Jinko 410w panels

5kw Huawei hybrid invertor

I'm getting quotes around €10,800 to €11,700.

This is before grants. Is it reasonable or am I getting fleeced here. I asked 4 to 5 companies and all are around the same

seems high for basic system.. and why a hybrid inverter if no battery?

then again, what's the consensus pricing guidance anymore? is the market too volatile (aka gouging) to have any guidance? 😐

Yea thought so too and such a big difference in price for similar setups.

The hybrid inventor was just to have an option to have a battery if there is too much exporting and might make it worth while. I was told the price between the hybrid and non-hybrid is around €800

But a Huawei inverter can only use one of their own or a LG battery. These are very expensive.

Don't get one of their hybrid inverters based on possibly upgrading later.

could get an Eddi or something similar instead, or more panels! 😂😆 and forget the battery, now with CEG\FIT in place

wondering if it’s worth getting the battery with Feed-In Tariff in place?

Regular contributors will know that I'm fairly pro-battery, not just for fiscal (making your money back) reasons, but also cause I think it's the right thing to do for the grid. That said, you need to do your sums if it's worth it for you.

Typical "rule of thumb" is that the size of the battery is your yearly consumption in kwhr/1000. E.g. if you use 5000 units a year, then a 5Kwhr is probably a decent match. If you consume more like say 10-12K etc, then batteries come into their own. If you are in about 3000-4000 units a year, it's much more debatable if you should get one. Again, that's just a rule of thumb.

Does that battery sizing take into account charging at night rates let's say quarter of day rate and avoiding using any or as little day rate as possible?

I consume about 17kwh per day and I have gone with a 10kWh battery. So in summer I hope to get all the way through the night on the charge from the previous day. But in winter I’ll obv charge it up at night and the 10kwh + whatever I generate during the day will hopefully get me most (but I suspect not all the way) through the worst production days. But some days in winter I expect to gen 4-5 KWh so it will be close.

I have the huawei battery, and I choose it for this reason, as I can add an additional 5kWh module on top if I decide 10 isn’t quite enough for the winter.

I’m still on a standard tarrif (I do have a smart meter) im still trying to decide if I should start discharging the battery as soon as it’s charged, or wait till the peak period in the evening as the point to start discharging.

Grab it and run

It's a "rule of thumb" not meant to be an exact equation - but yes that is the idea to cover your day rate from night time charging. Is it perfect? Hell no, but it's easy to come up with "some" sizing which doesn't involve Excel for people. In truth, to do it properly you should work out your consumption knowing what your user profile is for your house. Is there someone there for the daytime in the house, who can use solar? What load shifting can you do to night time, etc etc.

im completely clueless to all the ins and outs of solar just starting my research we have a large enough 5 bed detached house and are interested in solar. I emailed a company local to me and got this in return. Anyone give any insight as to whether it’s a good system or not. Does the pricing seem ok?

System size: 6.4KW - PV Panels – Leapton 400w by 16 - All black Panels.

Panel Mounting – Renusol

Inverter - Solis single phase 5G inverter.

Total cost: €10,120 including VAT.

SEAI Grant - €2,400

Price after grant - €7,780

Optional Hot water – €700 for Eddi Divertor 

Optional Battery – Add €3,500 for 5.1 CFE 

Warranties - 25 years for both performance and panel, 10 years on inverter & battery.

Whole system Workmanship warranty - 5 years.

Insurance – Included.

That's a good price considering some on here lately but get a 6kw inverter for that price and if they could do better on the battery and water diverter it would be as good as you will get nearly. The fact the company is local is a bonus if anything ever goes wrong or you want extra stuff done in the future.

Have a look at post #4048 a couple of posts above. That quote of yours is way out, have you put an inverter in that quote instead of a battery? You have 2 inverters listed. Huawei gear is not much better than the likes of Solis for a much lower price and better compatibility for future adding of batteries.

Eddi is cheap. Everything else is expensive
